Re: [Cppcms-users] razor like syntax for templates

[Lee E. <lee...@gm...>]

I looked into enhancing the <%= %> syntax a bit - and it is a bit tricky
since - especially if you think razor like:

with razor you expect things like this to work:

@for (int i;....){

<li>@i. some content...
}

the problem is that the current syntax only deals with data that comes from
the model - (by prefixing it in the generated cpp) or variables declared
using blocks like the <%foreach...%> block

i toyed around with the idea of performing a 'pascal like' with that will
allow the compiler to find the correct variable using the folowing search
order: local to template, then model, then template - but that forces a few
limitations: on template namings in order to support calling from one
template to another - so this turned into an issue. - but moving to a razor
like syntax can come with the restriction of only using one template in a
file - and use the @Render (and its siblings) to handle calls between files

if i can be of assistance - please let me know.

PS: Artyom what happened to the changes i made to cppcms_tmpl_cc? that
allowed for separate template compilation and use of header files? I
noticed that it got dropped somewhere in the versions - and i hadn't had
the time to resend it to you with updates.
